My software provider sent me an update tonight that the IRS e-filing system will be taking a holiday vacation beginning on December 26th and returning “sometime in early January; the exact date has not been announced.” This will impact business filers. Returns can still be submitted (they’ll be held by the software companies) and will be considered filed on the date submitted to the software providers.
The IRS has still yet to announce when 2013 personal tax returns can be filed (sometime between January 28th and February 4th).
